The fresh infusion of capital will be used to bolster the Elastifile's sales efforts amid a period of brisk growth. The company reported that more than 40 customers are using the company's "cross-cloud data fabric" technology.

Elastifile is headed by CEO and co-founder Amir Aharoni, formerly of Mobixell Networks and Optibase. Its CTO, Shahar Frank, co-founded flash storage systems maker XtremIO, which was acquired by EMC in 2012.

The company launched its flash- and cloud-enabled Elastifile Cloud File System platform in April. Combining the performance-enhancing capabilities of flash and multi-cloud support, the elastic infrastructure technology allows organizations to eliminate storage silos and extend critical workloads to the cloud.

Also key to the offering is the ability to "lift and shift" applications to the clouds without having to refactor them.

Elastifile includes data deduplication and compression at no additional cost and supports the three top cloud computing providers, Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform. In June, the company became an official Google Cloud Technology Partner, allowing customers to move stateful containers, applications and other on-premises workloads to the Google cloud and back without modification and with service-level agreement (SLAs) assurances intact.

"Elastifile has developed a cloud-scale distributed file system designed to free data locked inside storage silos so all users and workflows can access it instantly from anywhere," said Mark Long, president of Western Digital Capital, in a statement. "The company is addressing an important and growing challenge associated with traditional storage architectures. We strongly support their efforts and are pleased to expand our ongoing strategic relationship."

Lead investor Western Digital has been busy on the deal-making front lately.

Also in August, Western Digital snapped up cloud content storage and sharing specialist Upthere for an undisclosed amount. In May 2016, Western Digital completed its acquisition of flash chip maker and solid-state drive (SSD) provider of SanDisk, a transaction valued at an estimated $19 billion.
